output voltage of a full wave bridge rectifier

[Kick]

hii all,
how can I calculate output voltage of full wave bridge rectifier??

is this correct equation for that: Vmax= Vrms x 1.414 and Vdc= 0.318 x Vmax.

Hi,

if you place a capacitor directely to the outputs of a bridge rectifier you will measure peak voltage.

if you place a 2 resistor voltage divider between rectifier and capacitor you will see (about) average voltage. That is 0.6366 of peak voltage (if i remember right).

it depends on the circuit.

That is 0.6366 of peak voltage

Exactly 2/pi, for an ideal sine voltage.
